Answer:

\(U=\pm 0.382N\)

Explanation:

From the question we are told that:

Resolution: 0.25 N

Range: 0 to 100 N

Linearity error: within 0.20 N over range

Hysteresis error: within 0.30 N over range

Generally the equation for Stage Uncertainty is mathematically given by

\(U=\sqrt{u_0^2+u_T^2}\)

Where

\(u_0=Zero\ order\ uncertainty\)

\(u_0=\pm 0.5*0.25\)

\(u_0=\pm=0.125\)

And

u_T=Total instrumental Uncertainty

\(u_T=\sqrt{l_e^2+h_e^2}\)

Where

l_e=Error of linearity

h_e=Error due to hysteresis

Hence

\(u_T=\sqrt{0.20^2+0.30^2}\)

\(u_T=\pm 0.36\)

Therefore

\(U=\sqrt{(0.125)^2+0.36^2}\)

\(U=\pm 0.382N\)

a. a = 12 is the solution to the given congruence relation. b. the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

(a) The main answer: The integer a that satisfies a ≡ -15 (mod 27) is 12.

To find the value of a, we need to consider the congruence relation a ≡ -15 (mod 27). This means that a and -15 have the same remainder when divided by 27.

To determine the value of a, we can add multiples of 27 to -15 until we find a number that falls within the range of {0, 1,..., 26}. By adding 27 to -15, we get 12. Therefore, a = 12 is the solution to the given congruence relation.

(b) The main answer: The positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

Supporting explanation: Two integers are relatively prime if their greatest common divisor (GCD) is 1. In this case, we are looking for positive integers that have no common factors with 12 other than 1.

To determine which numbers satisfy this condition, we can examine each positive integer less than 12 and calculate its GCD with 12.

For 1, the GCD(1, 12) = 1, which means it is relatively prime to 12.

For 2, the GCD(2, 12) = 2, so it is not relatively prime to 12.

For 3, the GCD(3, 12) = 3, so it is not relatively prime to 12.

For 4, the GCD(4, 12) = 4, so it is not relatively prime to 12.

For 5, the GCD(5, 12) = 1, which means it is relatively prime to 12.

For 6, the GCD(6, 12) = 6, so it is not relatively prime to 12.

For 7, the GCD(7, 12) = 1, which means it is relatively prime to 12.

For 8, the GCD(8, 12) = 4, so it is not relatively prime to 12.

For 9, the GCD(9, 12) = 3, so it is not relatively prime to 12.

For 10, the GCD(10, 12) = 2, so it is not relatively prime to 12.

For 11, the GCD(11, 12) = 1, which means it is relatively prime to 12.

Therefore, the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

The correct answer is that a hydraulic power system is used for large amounts of force.

Explanation:

A pneumatic power system would be much more effective at focusing on a specific area. One person would be able to hold a pneumatic system, as the design can be made small. It can even be designed with a simple on/off switch.

The hydraulic system would fail because hydraulic power system is used for large amounts of force.

Energy or signals are transported through the static or dynamic forces of liquids in hydraulic power transmission systems. These fluid power systems are a subset of them. The two types of fluid power are hydraulics and pneumatics. The valves aid in controlling the liquid's flow and relieving pressure when necessary.

Pumps are used in hydraulic systems to force hydraulic fluid through the system and generate fluid power. The fluid flows to the cylinder, where the hydraulic energy is converted back into mechanical energy, after passing through the valves.

Therefore, Due to the hydraulic system's need for high levels of force, it would malfunction.

The continuity equation allows finding the results for the speed and flow of the outlet pipe are:

Fluid mechanics studies the movement and fluid dynamics, it is described  by two fundamental relationships:

          \(P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2\)  

Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.

            \(A_1v_1 = A_2 v_2\)

Where A₁ and A₂ is the area of ​​the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet

They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity

         \(v_2 = ( \frac{A_1}{A_2} )^2 \ v_1\)  

the cross section of the tavern is

        A = \(\pi r^2 = \pi \ d^2/4\)  

Where r is the radius and d is the diameter

Let's substitutes

        \(v_2 = (\frac{d_1}{d_2} )^2 \ v_1\)  

        \(v_2 = (\frac{0.02}{0.1} )^2 \ 10\)  

        v₂ = 0.4 m / s

The flow  (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore

        Q = A v

        Q = \(\pi \frac{d_2^2}{4} \ v_2\)π d2 ^ 2 v2

        Q = \(\pi \ \frac{0.1^2}{4} \ 0.4\)

        Q = 3.14 10⁻³ m ^ 3 / s

As the transported liquid is water

         1 liter water = 1 kg

Consequently

         1 m³ = 1000 liter = 1000 kg of water

Let's reduce the flow

         Q = 3.14 10⁻³ m³/s ( \(\frac{10^3 kg}{1 m^3}\) )

         Q = 3.14 kg / s

The center distance, gear ratio, and circular pitch of a spur gearset with 17 teeth on the pinion and 51 teeth on the gear are 5.667 in., 3, and 0.524 in., respectively.

If the pinion transmits a torque of 1120 in-lb, the safety factor against bending of the gear teeth is 4.38 using an overload factor of 1.0 and a through-hardened FL-4405 alloy powder metal material.

(a) The center distance is given by the equation:

cd = (p1 + p2)/2,

where p1 and p2 are the pitch diameters of the pinion and gear, respectively.

The pitch diameter is given by:

dp = n/p,

where n is the number of teeth and p is the diametral pitch.

The gear ratio is given by:

gr = n2/n1,

where n1 and n2 are the number of teeth on the pinion and gear, respectively.

The circular pitch is given by:

pc = π/p.

Using these equations with the given values, we get:

p1 = 17/6 = 2.833 in.

p2 = 51/6 = 8.5 in.

cd = (2.833 + 8.5)/2 = 5.667 in.

gr = 51/17 = 3

pc = π/6 = 0.524 in.

Therefore, the center distance is 5.667 in., the gear ratio is 3, and the circular pitch is 0.524 in.

(b) The bending stress on the gear teeth is given by:

σb = Ks Wt Fb / J,

where Ks is the stress concentration factor, Wt is the transverse load on the teeth, Fb is the bending factor, and J is the geometry factor.

The transverse load on the teeth is given by:

Wt = T2 / (d2b cos(α)),

where T2 is the transmitted torque, db is the base diameter of the gear, and α is the pressure angle.

The bending factor is given by:

Fb = Yb / (0.1544 + 1.912/p),

where Yb is the Lewis form factor.

The geometry factor is given by:

J = (1/2) (1/r1 + 1/r2 - cos(α)/p),

where r1 and r2 are the radii of curvature of the gear teeth.

Using these equations with the given values, we get:

db = p2 cos(α) = 8.155 in.

Wt = 1120 / (8.155 cos(20°)) = 80.92 lb.

Yb = 0.354 - 0.912/p = 0.284

J = (1/2) (1/2.4167 + 1/7.2917 - cos(20°)/6) = 0.0371 in.

σb = (10)(1.5)(80.92)(0.284) / (0.0371) = 6594 psi.

The material FL-4405 has a yield strength of 150 ksi. Using a safety factor of 1.0, the allowable stress is:

σallow = 150,000 psi / 1.0 = 150,000 psi.

Therefore, the safety factor against bending of the gear teeth is:

ns = σallow / σb = 150,000 / 6594 = 22.77.
